Mutable refs for simonecorsi/mawesome including latest, v1, v2, and v2.2.0 currently resolve to a composite action that installs Bun and always runs an obfuscated JavaScript payload, exposing GitHub Actions runners that still trust those tags.
An attacker force-pushed a malicious composite action into codfish/semantic-release-action and moved fifteen published tags to that commit, exposing GitHub Actions runners that still trusted mutable refs such as v3, v4, and v5.
All 53 reviewed tags for actions-cool/issues-helper and all 15 tags for actions-cool/maintain-one-comment were moved to dangling imposter commits that scraped GitHub Actions runner memory and exfiltrated credentials. GitHub now blocks access to both repositories.
